Carbon Activated Pre-Filter 4-pack for use with the Germ Guardian FLT4825 HEPA Filter, AC4800 Series, Filter B By Complete Filtration Services

Does the job its designed for.

I am beyond pleased with this product. I have had asthma since 18, now 31, & over the past 2 years Ive needed to use my rescue inhaler anywhere from 2-6 puffs per day! THE FIRST NIGHT I TURNED IT ON, IT WORKED. I didnt use my inhaler after work, before bed, or after I woke up in the morning! Its quiet, compact, and light - which makes it easy to move from my living room to bedroom. I would absolutely recommend this air purifier to anyone.

I bought this to go with the filter that it lists in the title but I had to cut it to fit the filter. Not completely compatible

Product is good and performs well but gets folded up and sent in a bag, leaving the filters crumpled and creased and difficult to make them stay in place and fitwell on the larger filter. I set mine underneath a book for several weeks to get it to flatten out. There really should be another velcro spot halfway down the filter to hold it more securely. Otherwise the product works quite well.

Very easy to use and they work great! Thank you

Just what I was looking for my air purifier it was easier to find on here thank you

Changing this pre-filter on a regular basis will extend the life of the hepa filter. Also, keeps the air cleaner. Well worth the modest cost.
